CABLE-GRIP.

Specification of Letters Patent.

Patented Aug. 3, 1915.

Application filed December 4, 1914. Serial No. 875,502.

To all whom it may concern Be it known that I, THOMAS DE WIT RIvERs, a citizen of the United States, residing at Valdosta, in the county of Lowndes and State of Georgia, have invented a new and useful Cable-Grip, of which the follow ing is a specification.

The device forming the subject matter of this application is a grip adapted to hold a wire while the same is being" stretched, the structure being of use primarily but not exclusively in the hands of linemen.

One object of the invention is to provide a novel means whereby the cooperating gripping jaws may be assembled with the link upon which the jaws are mounted to slide.

Another object of the invention is so to construct the link that the gripping faces of the jaws will define an acute angle the bisecting line of which extends transversely of the plane defined by the-link, to the end that the extremity of the wire may not drop through the link, between the jaws.

It is within the scope of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

lVith the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing :Figure 1 shows the invention in top plan, parts being broken away and sectioned; Fig. 2 is a side elevation; Fig. 3 is an end elevation.

The device herein disclosed preferably is fashioned from metal throughout and embodies a link 1 provided at one end with a hole 2 or any other suitable means whereby the link may be assembled with a stretching element (not shown). In the link 1 is formed a tapered opening 3 defining converging side arms 4.

A pair of cooperating jaws 5 are provided, the jaws 5 being equipped in their outer faces with grooves 6 which receive the side arms 4 of the link slidably. The grooves as clearly shown in Fig. 2 taper toward their ends. Into the grooves 6 are inserted, with a close driving fit, fillers 7 which ordinarily are fashioned from brass, the aws 5 prefer ably being made of iron or steel. The fillers 7 taper toward their ends as shown in Fig. 2 and fit closely in the tapered grooves 6. The adjacent or inner faces 8 of the jaws 5 .areserrated as shown, in order to increase then is slid in the direction of the arrow A toward the narrower end of the tapered opening 3 in the link 1. leaves, the wider end of the tapered opening 3 in the link 1 unencumbered, so that the other jaw may be placed therein, the last mentioned jaw being moved transversely until its groove 6 receives the corresponding side arm 4. Then the last specified jaw 5 is moved toward the smaller end of the opening 3 in the direction of the arrow A and both jaws are adjusted longitudinally of the link 1 until their serrated faces 8 are in contact. Thus, one jaw 5 acts as an anvil for the other, and when the structure is set up edgewise, one of the fillers 7 may be compressed or hammered into the corresponding groove 6. The structure is then reversed and the other filler 7 is mounted in place. The device is then in operative condition.

Owing to the fact that the grooves 6 taper toward their ends and owing tothe fact that the fillers 7 are correspondingly shaped and taper toward their ends as shown in Fig. 2, the fillers are held securely in place in the grooves and there will be no tendency for relative longitudinal movement between the fillers 7 and the jaws 5 when the latter are slid on the side arm 4 of the link 1. Because the link 1 is bowed transversely as clearly shown at 9 in Fig. 3, the adjacent or inner faces 8 of the jaws 5 define the acute angle 10 and in this angle the wire 11 is lodged. Owing to the fact that the faces 8 define the angle 10, the free end of the wire cannot slip downwardly through or between the jaws 5 before the jaws are tightened on the wire, it being understood that this tightening operation is brought about by moving the jaws 5 This operation on the arms 4 in the direction of the arrow A until the wire 11 is firmly gripped and held between the faces'8 of the aws.

It is to be observed that in this structure no set screws, bolts or other elements adaptedto become loosened are employed Having thus described the invention, what is claimed is z- 1. In a Wire grip, a link having a tapered opening defining a pair of side arms';'a pair of cooperating jaws having grooves in their outer faces, the grooves receiving the side arms slidably, the opening being of sulficient length whereby one jawmay' be placed within the opening and be moved transversely to cause the groove in said jaw to receive one arm when the other arm is in the groove of the other jaw andwhensaid-other jaw is slid toward the narrower end of the opening; and fillers mounted in the grooves and cooperating with the outer edges of the arms.

2. In a wire grip, a link having tapered opening and defining a pair of-sid'e arms; a pair of cooperating jawshaving grooves in their outer faces, the grooves receiving the sidearms slidably, the opening being of sufficient length whereby one jaw may be placed within the opening and be moved transversely to cause the groove in said jaw to receive one arm when the other arm is in the groove of the other jaw and when said other jaw isslid toward the narrower end of the opening; fillers mounted in the grooves and cooperating with the outer edges of the arms, the grooves being tapered toward their ends, and the fillers being tapered to fit in the grooves, thereby preventing relative longitudinal movement between the fillers-and the jaws when the jaws move longitudinally of the arms.

3. In awire grip, a link having side arms;

jaws-mounted toslide on the arms, the inner surfaces of the jaws cooperating to form gripping faces, the link being bowed transversely to cause the gripping faces of the jaws-to define an" acute angle the bisecting line of which extends transversely of the plane defined by the link.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
